UTF-16
Sign in to saveAlso known as 16-bit Unicode Transformation Format, Unicode Transformation Format – 16-bit, Unicode Transformation Format - 16-bit, UTF16, UTF_16
UTF-16 (16-bit Unicode Transformation Format) is a character encoding that supports all 1,112,064 valid code points of Unicode. The encoding is variable-length as code points are encoded with one or two code units. UTF-16 arose from an earlier obsolete fixed-width 16-bit encoding now known as UCS-2 (for 2-byte Universal Character Set), once it became clear that more than 216 (65,536) code points were needed, including most emoji and important CJK characters such as for personal and place names.

UTF-16是Unicode字符编码五层次模型的第三层：字符编码表（Character Encoding Form，也称为"storage format"）的一种实现方式。即把Unicode字符集的抽象码位映射为16位长的整数（即码元）的序列，用于数据存储或传递。Unicode字符的码位，需要1个或者2个16位长的码元来表示，因此这是一个变长表示。 UTF是"Unicode/UCS Transformation Format"的首字母缩写，即把Unicode字符转换为某種格式之意。UTF-16正式定義於ISO/IEC 10646-1的附錄C，而RFC2781也定義了相似的做法。
